IDF troops found the white van which was driven by a Palestinian motorist who plowed into three soldiers who were standing on the side of the road in the Gush Etzion bloc on Wednesday night.
The vehicle was found abandoned near the West Bank village of El Arub.
Earlier on Wednesday, security forces pinpointed a vehicle that looked similar to the white van, though no signs of damage or evidence indicating suspicious activity was found.
Three IDF soldiers were injured Wednesday night after a Palestinian vehicle slammed into them on Route 60 southwest of Bethlehem in an attempt to target the Israeli forces, the IDF spokesperson's office said.
A freight truck with Palestinian license plates hit the three IDF soldiers, wounding one seriously and two moderately in what he IDF said was a terror attack, making it the second such vehicular attack targeting Israelis on Wednesday.
The perpetrating vehicle fled the scene immediately after the attack, and security forces set up roadblocks and launched searches of the area of the southern West Bank.
The soldiers were apparently near a military position when they were attacked.
Magen David Adom spokesman Zaki Heller said paramedics treated three Israelis aged 20, one with serious chest wounds, and two moderately injured men with broken bones and injuries in their limbs. The wounded were evacuated to the Hadassan Ein Kerem hospital in Jerusalem.
